To all whom it may concern:

Be it known that I, WALTER LAwsoN Anims. o subject of the. King of Great lritnin. residing' nt New Haven, in the county oi" New Haven :ind State of Connecticut. have invented u non' und useful Ifnprovmnent in Auton'iobile Bumpers; and I do herebyr dechire the following, when token in connection with the ueeomponying drow ings, und the chnroeters of reference marked thereon, to be n full, clear, and exact description ot' the some', und which said drawings constitute part ofthis application, and repu resent, in- I Fig. l u. plan View, partly in section, of nn automobile bumper constructed in accordance with my invention.

Fig. 5 a sectional View on the line 5 5 of F 2 This invention relates to improvement in lbumpers for outomobiies, such as are commonly arranged nt the iront and boek to take the impact, in ense of collision. The object of the invention is to rovide cushions for the bumper which wi be suiiieiently rigid to withstand the strain and yet so yielding that the impact of the bnmier against on obstruction wilt not import un ue shook to the enr, und the invention consists in the construction as hereinafter described und porticulorly recited in the Claims.

In carrying ont my invention, .l 'employ blocks 10 of rubber, similar in construction to the rubber' blocks shown in my suspension device for automobiles Vpatented in the United States November 187 1924, No. 1,515,716. These blocks are formed on opposite sides with ribs 11 and grooves 12, preferably erro-n ed redini nndjtbrough the center of the lock is u. o eorencebpening 13. These blocks are located between inversely turned on s 14 and 15 struck up from sheet- 59 metal. ese cops are provided with alten mitin ribs 16 and grooves tiene. referably t ese ribs and grooves will be ernied by eorrognting strips of eheetmete which are secured to the oops by spot weiding, or otherwise. These cups have Monnier Hongos i0'. ig. 6 n side View of the block, detnebed.'

18, to enter the centro] opening 12; blocks. y The cups 14 are connected by '7 otherwise, with suspensionpietes phxtes nre connerted with the outsioo chassis-traine, being` eonnecteii with 'the shzwkle-bolts 20. These pint/es oise sorry cylinders 21, into which burnpenrf Y extend, these bumper-rods saigner* bumper-bar 23 nt their outer eneis.

The cups 15 have attached te there si mental-plates 24, formed with university projerting fingers 25 extending into the peth olf the bumper-rods 22. The block is heiei in place between the en'ps by :i bolt which bears at one end on the suspensio-n-oiete :md carries a nut 27 bearing on o ciiiin j' plete 28, forcing o. fiber Washer Fl@ eg the outer feces of the cups l5.

An i1nvn1d-thri1stnpon the biunperbor pushes the bumper-rods inward, ogeinst the ingers 25, which turn the cups i5 sind benne give oA torsional movement to the bloeit it?. This takes the shook ot' impact ngninst the bumper-bnr, but is so yielding anni ins? in its movement that nrnr'tieolly no shock is imparted to the cor, the oetion of the bloeit beine' the sinne ns the hioehs used in the sus pension device ot' the patent nbove referto@ to.

Thilo l' prefer. to forni the ribs end grooves in the block radially. it is that their direction might be slightini,v so long :is they provide tor resistir. sional stroin` :ind instead o forming the ribs und grooves for theeups, it is obvious, with.- out iliustrution, that the oops might be formed with integr-,il ribs and groores.

1t is obvious, oise, that the form of bumper-bar may be varied to moet the rea qnirenients of construction or ornementetion oi' the cnrs to wlnh they ore eppieri..

I claim:

1. A bumper for automobiles, eomprising 1 tilting ribs und ,groovee,"two ong-ebene@ .roei

provided with ribs and grooves correspond ing to the ribs and grooves in the block, which is located between them, means for rigidhv mountingr one of said members, :1 linger connected with the other member, "a tubular hearing mounted in line with said .tingen u. bumper-rod extending Ythrough said bearing,r into engagement with sind finger,

1 and a bumper-bur connected with the outer end of said bumper-rod.

3. A bumper for automobiles, comprising :i rubbeigbloekformed on the opposite sides wit-h ribs `and grooves, reversely-arrunged cups, each "having ribs and grooves formed of sheet-metal and connected with said cups und corresponding with the ribs and grooves En Suid block, one of said cups rigidly connected with a suspension-plate, said suspension-plate provided with a horizontally-arranged, tubular hearing,

tending through said bearing, a har Supported ut the outer end ot' said bumper-rod,
